Saving values to another post on post save

I have the custom post type ‘machines’.

Machines has two custom fields of the type post object: “company” and “seller”.

On saving the machine post type, I want to update the company post (which has a ‘sellers’ repeater and a ‘machines’ repeater) with
the ‘seller’ id selected for ‘machine’ and the ‘machine’ id itself.

Also I want to update the ‘seller’ post’s ‘company’ custom field with the ‘company’ post type id that has been selected for the machine post type.

I have written the following function to accomplish this:

add_action('save_post_machines', 'associate_machine', 10, 3);

function associate_machine($post_ID){
        
    //Add seller and machine to company page
        $company = get_field('field_60f1861f1b262', $post_ID); //company ID
        $seller = get_field('field_60f186361b263', $post_ID);  //seller ID
        $whichs = ['machine' , 'seller'];
        foreach($whichs as $which):
            
            $post_ID = $which == 'machine' ? $post_ID : $seller;

            $repeaterValues = [];
                if(have_rows($which.'s', $company)): //Machines or sellers repeater
                    while(have_rows($which.'s',  $company)):
                        the_row();
                    $repeaterValues[] = get_sub_field($which, $company);
                    endwhile;
                else:
                    add_row($which.'s', array($which => $post_ID), $company);
                endif;

                //if machine or seller ID is already inserted, simply stop here
                if(in_array($post_ID, $repeaterValues)):
                elseif(!in_array($post_ID, $repeaterValues) && !empty($repeaterValues)): // if not, add it
                    add_row($which.'s', array($which => $post_ID), $company);
                endif;

        endforeach; 

        //Add company to seller:
        update_field('company', $company, $seller);

But instead of having the seller id in the sellers repeater, I only get an empty row.

Additionally, and this is strange: I was testing this on my staging site, and it was working. Then uploading the same code to live, it is not. (I made a compare of all theme files of live and staging and matched them up 100%, and still.

I also checked if there were any plugins that were not updated on the staging site, still no change.

So I have worked on this for a while and can’t seem to find what I am missing.

Any insights would be appreciated.

The problem was that the custom field data of the machine post was probably not saved yet.

using add_action('save_post_machines', 'associate_machine', 10, 3);

using

add_action('acf/save_post', 'associate_machine', 11);

instead of post save, resolved the problem.

What I had trouble finding before is that the priority should apparently be > 10.
